We have a store nearby that sells Weld-On 3, 4 and others and I was wondering what one is best? I believe #3 was always popular but I am not sure.
I have always used Tenax but the price of this stuff is far better.

I use Plast I Weld and Tenax and get excelent results. The bottles last me a very long time and i use them for about 90% of my gluing and applied with a Touch N Flow applicator.
I take it weld on is a brand name . Is it the type of glue that melts the two halves together
I used to used weld-on all the time but haven’t seen it in years. Either our shop here doesn’t carry it anymore, or I just keep missing the shipments.
Hi;
I used to till I discovered the Tamiya line of glues .Now I use them exclusively .I still use Testors , but haven’t seen Weld-On #3 for quite a while . T.B.
I’ve never used Weld-On, nor even seen it (I followed your link, to take a look).
For liquid styrene cement, I use Plastruct’s Weldene and Bondene, they work pretty well for me.
I have never used weld on, I do use Tenax and Tamiya quite a bit. On occasion I will use plasti strut or the flexi file brands. I like that style of glue and I try to keep a few different brands around as they work better depending on the plastic.
on a side not, I love TAP plastic, I hit the store up every chance I get
Several years ago, I was looking for a cheaper liquid plastic glue and came across Methylene Chloride at a plastics supplier. For all practical purposes, it is the same as Weld On #3 but much cheaper (at that time Weld On #3 was something like $3.95 for 2 ounces, while Methylene Chloride was 5 bucks for a Quart. The last gallon I bought cost me about 25 dollars and will last 3 to 4 years. I have a couple of empty Weld On jars that I fill and keep on my modeling desk (the rest goes into an old fridge that I store volatile liquids in. Check your local phone directory for a plastics distributor and give them a call.
I was intorduced to Weld On 3 back in the early 80s and was hooked on this type of liquid cement. I have not seen it for several years and now use Pro Weld, which is practically identical. I also use Tenex but its kind of harsh on some plastics.
Weld-On #3 is now sold as Sci-Grip #3. Same stuff, different name. There are two types of ‘weld-on’…#3 and #4. #3 is ‘hotter’ than #4 and, therefore, sets quicker. It is, however, not as quick-setting as Tenax. The active ingredient is methylene chloride, which means it’s a hazardous material. BE SURE to read the MSDS on this stuff!! Use it with PLENTY of ventilation!!!
